> URL: https://issues.apache.org/jira/browse/PDFBOX-4770
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel, Text extraction
> Affects Versions: 2.0.11
> Environment: Java 8, macOS Mojave 10.14.6
> Reporter: Samuel Litster
> Priority: Major
>
> Our system needs to extract text from pdfs. It's been working for over a
> year, but today we started seeing errors when we tried to process some pdfs.
> This has only affected a small number of pdfs so far, but when it does come
> up we are unable to extract the text. Following is the pertinent part of the
> stacktrace:

> We have no control over the content of the pdfs, but we have to be able to

> configure PDFBox to handle this properly?
> The offending pdfs are over 60 MB so I can't attach one to this issue.
